“…About 50% of the energy is lost due to irreversibilities [185][186][187] and rejection of heat to satisfy the Second Law of Thermodynamics, however with waste heat recovery (WHR), some of this energy can be recovered from the exhaust gases, which will lead to less emissions and lower fuel consumption [116]. Potential power generation can come from: (1) jacket water (5.2%), (2) air cooler (16.5%) and (3) exhaust gases (25.5%) [188].…”

This review paper examines the possible pathways and possible technologies available that will help the shipping sector achieve the International Maritime Organization’s (IMO) deep decarbonization targets by 2050. There has been increased interest from important stakeholders regarding deep decarbonization, evidenced by market surveys conducted by Shell and Deloitte. However, deep decarbonization will require financial incentives and policies at an international and regional level given the maritime sector’s ~3% contribution to green house gas (GHG) emissions. The review paper, based on research articles and grey literature, discusses technoeconomic problems and/or benefits for technologies that will help the shipping sector achieve the IMO’s targets. The review presents a discussion on the recent literature regarding alternative fuels (nuclear, hydrogen, ammonia, methanol), renewable energy sources (biofuels, wind, solar), the maturity of technologies (fuel cells, internal combustion engines) as well as technical and operational strategies to reduce fuel consumption for new and existing ships (slow steaming, cleaning and coating, waste heat recovery, hull and propeller design). The IMO’s 2050 targets will be achieved via radical technology shift together with the aid of social pressure, financial incentives, regulatory and legislative reforms at the local, regional and international level.

One of the major challenges facing the maritime sector today is the transition to zero emission carbonneutral vessels. In particular, work vessels such as dredging vessels are required to operate worldwide and under heavy conditions. These vessels have a high power density, limited on-board space, require often a large autonomy, and therefore will need very energy dense fuels. This article presents an environmental and economic assessment of four cutter suction dredger drive system design alternatives with the life cycle performance assessment tool. This tool includes the most important environmental factors as well as the net present value. The effect of emission costs and fuel price developments may be taken into account with scenarios, and this article illustrates that they have a large effect on the economic viability of future zero emission vessels. A combination of clean fuels, new prime mover technologies, efficient design and effective system integration has the potential to achieve zero emissions while maintaining the vessels' functionality. However, technology alone cannot solve the complex challenge of energy transition in the maritime sector. In order to make zero emission designs economically viable, a system wide integration is needed, meaning cooperation in the value chain and effective policies.

This article aims to model and optimize the fire tube Heat Recovery Steam Generator (HRSG) used in a gas microturbine cogeneration of heat and power system. Here, six cases including a finless and finned tube (solid and serrated) HRSGs with the inline and staggered arrangements are optimized and compared using techno-economic assessment. Optimization of HRSG was carried out by applying two objective functions of minimizing the total annual cost as well as maximizing the exergy efficiency. Nondominated Sorting Genetic Algorithm II is used to find out the optimal values of design variables. The TOPSIS decision-making process is employed to choose the optimum point of the Pareto front. A 600 kW gas microturbine cogeneration plant is considered as a case study. The results revealed that the finless tube HRSG with an inline arrangement has the lower pinch and approach temperatures (3.5 • C and 3.1 • C, respectively), the higher steam mass flow rate (12.7%), the lower total annual cost (64 096$/year), and the higher exergy efficiency (60.6%). It is also found that using the staggered arrangement tube banks along with the solid fins in HRSG leads the total annual cost, the steam mass flow rate, and exergy efficiency increase up to 41.6%, 100%, and 12.6%, respectively. This means that the thermodynamic performance improvement will compensate the total annual cost increment. Furthermore, it is demonstrated that HRSG with solid fins and staggered arrangement with total annual costs of (90 810$/year), exergy efficiency of (73.2%), and steam mass flow rate of (4680 kg/h) has the best performance in comparison with other finned tube cases.
